All files are closed and opended again (but that isn't the way the program works, you say). I tried to kill -9 the job several times, but the error was not reproducable (random 1 returns 0..9 randomly): # while true; do sleep $((55 + $(random 1) )); kill -9 $(ps aux | grep -v grep | grep uptim | tr -s ' ' | cut -d' ' -f2); sleep 3; /etc/init.d/uptimed start; cat /var/spool/uptimed/records; done > Out of curiosity, what filesystem are you using on your system?

XFS's journaling procedures are similar to > the "writeback" level of ext3. The part "unwritten data blocks are zeroed" could be the problem. What do you think? I will set the update interval to 600s and pray ;-) cu Peter
